In reply to:

Steve Sanacore: As sensor size gets larger, (for better image quality), lenses will follow. You can't have a tiny long fast AF lens on a 1" sensor without changing the laws of physics. IMO you still can't beat M4/3 systems for the best compromise of size vs.image quality.

That´s questionable. An 1" sensor camera with 24-100mm f1,8-2,8 lens is actually better choice than f3,5-5,6 lens on M4/3 camera and even on APSC.
F1,8-2,8 on 1" sensor equals to f4,9-7,6 on FF
F3,5-5,6 on 4/3" sensor equals to f7-11,2 on FF
F3,5-5,6 on APSC sensor equals to f5,3-8,4 on FF.
Of course bigger sensor has better DR, lower noise, handler high ISO better etc., however with bright lens you don´t need to get your ISO high. So a 1" sensor compact with bright lens (like the RX100 or DL24-85) is a better option than M4/3 CSC with kit lens. To get more out of 4/3 sensor you need a fast lens, but in this case it´s no longer small or pocketable.

Morten Rasmussen: That's amazing!

quote: "The RX100 III and IV meet the size and EVF requirements but are just too limited in terms of zoom."

and along comes the "fill gap" model from Nikon, hooray!!!!

But wait the zoomrange is even smaller than the RX100 iii and iv!!!!

Why on earth does the RX100 not qualify then?? I don't get it. I knov the Nikon Compact has some features in terms of wifi/bluetooth, that is nifty, but that's has got nothing to do with the camera as a mean to take pictures!

This is another example of Dpreview being so Canon and Nikon-centric, which again and again reminds me that their reviews are biased in a way, that makes it unusable.

just my 2 c.

The G7x was pathetically slow (2 fps?), but the Mark II can shoot RAW at 8 fps, so it should compete nicely now.
While below I wonder about general demand for long zoom, I also think 70mm eq.(RX100 III/IV) is pretty short. My universal walkaround lens is 17-70mm (25-105mm eq.), anything shorter is a bit too limiting. However when I had the Canon S100, it´s 24-120mm range was completely OK (this equals to 16-80mm on APSC, which is an ideal allrounder).
Just my 2c.

The Squire: The death of 1/2.3" (in anything but camera phones) cannot come too soon.

Now the 1" sensor is well established in big/medium-sized compacts, I'd love to see more products with 1/1.8" 2/3" sensors, for truly small cameras.

For example...

I love the size of my aging Sony TX5 - I'm sure Sony could cram a 1/1.8" sensor in there, add RAW and 4K video.

Plz?

1/1,8" sensor wouldn´t make much of a difference compared to 1/2,3" sensor in smartphones (like Xperia Z5). The common standard n enthusiast compacts has been the 1/1,7" sensor which allowed really tiny cameras (see Canon´s S-series) and that is being abandoned now. I can see the point of pocketable ultrazoom with 1/1,7" sensor with bright and long lens, e.g. 25-250mm f1,8-2,8. However now when there is Panasonic TZ100 with similar specs, a lot larger sensor (despite having slower lens), I don´t believe it would sell well.

sbansban: The biggest problems I still have with the current crop of zoom compacts (whether those with 1" or sightly smaller sensors) are their slow lenses that struggle to freeze subject motion especially in less than ideal light. I am hoping we will soon see (within just a few more years) cameras the size of ZS100 that have 10X or higher zoom and F1.4-F2.0 lenses. Is that too much to ask?

sbansban: what cameras do you mean? Since the majority of recent enthusiast compacts has really fast lenses (typically f1,8-2,8).
But if you mean an 1" sensor ultrazoom with 10x or bigger zoom and expect luminosity of f1,4, well, that really is a problem. Not that it was impossible, but the camera (lens) would be huge. Remember, f-number = focal length/diameter of entrance pupil.

I wonder why are compact camera buyers so obsessed with looooong zoom. Once I had a pocketable compact (Canon S100) and despite it had only 120mm at tele end, I was hardly able to get a picture anytime but in bright sunny day because of luminosity f5,9 at tele end. I know a good OIS can do a lot but usability of a camera at 720mm eq. and f6,3 seems very limited to me.
Like many of us I am often asked to advise a camera and the demands are always the same: small, pocketable, with good image quality AND with long zoom. I tend to recommend enthusiast compacts like RX100 et al, but many people reject it because of short zoom. However people who took my advise were very satisfied with the outcome and didn´t regret it (and to their surprise they didn´t miss the huge zoom).

Sure, an EVF would have helped K-01 a little. But would it have been enough to turn a flop into success story? I don´t think so. People bashed K-01 for its design, weight and size and that it had to use big DSLR lenses. And all those caveats are here with these Sigmas. So an EVF is nice to have (for me an inevitable thing in every camera above 200 euros), but it won´t help.

In reply to:

Steve Photographer: Always nice to hear of MFT lens additions. But what I really need from panasonic is a fast aperture, wide prime that is image stabilised. 12mm or 10.5mm would be great. Image stabilisation in this type of lens would not only allow handheld stills in lower light (or lower ISO), while also permitting indoor video on the hoof - without the faf of a rig. Of course IBIS is the holy grail but this isn't available in Panasonic cameras yet, at least for 4K shooting.

How about the GX8, doesn´t it have IBIS?

In reply to:

ozturert: Nice. If it's optically better than Oly 12-50mm, then it's a better option.

Well maybe for someone (me for instance) the gain at wide end is worth more than the loss at tele end. 28mm eq. is far too limiting.
Btw. I do not believe that a 10x zoom lens will be optically better than a 5x zoom.

Link | Posted on Feb 24, 2016 at 12:03 UTC

Given the current standard zooms for M4/3 this one is definitely the most interesting. The old 14-42 kit lenses are not wide enough and optically mediocre (well, a kit lens). The 12-32mm is wide, however too short. The 12-50mm is both sufficiently wide and long, but too slow. This one is wider than the kit zoom and longer than other two, so definitely the most interesting cheap zoom (well, cheap in comparison to Pro 12-40mm lens). So basically a counterpart to popular DLSR zooms like 15-85/16-85mm from N/C/P.
However I cannot get rid of a feeling that Pana could have used the advantage of smaller sensor and make a bit faster lens, e.g. a constant f4. This would fit nicely between f2,8 zooms (12-35, 12-40) and slow variable aperture kit lenses.

@HowaboutRAW: obviously people can multiply by 1,3. The point is manufacturers make lenses suited for either FF or for APSC. So you have a typical 24-70mm lens for FF and it´s counterpart 16-50mm for APSC, giving similar eq. FL. But APSH changes things a lot, e.g. the 16-50 lens would be 21-65mm eq., which is quite unusual.
Btw. do you really believe that EVF will turn a fail (K-01) to success (quattro)? Well dream on. ;-) In my opinion it´s exactly the same: mirrorless as big as a DSLR and having the same big DSLR lenses and weird (if not saying ugly) design. Plus contrary to K-01 for the quattros there are solely Sigma SA lenses (whereas for K-01 there were lenses from Sigma, Tamron etc.).
So we can come back to this topic in a year and see whether the quattros are more successcul than K-01. I bet they won´t.

One more thing: it will be interesting to calculate the lens equivalence on APSH body. We are used to calculate with 1,5x crop factor (APS-C), however things will be a lot different with APS-H sensor and its 1,3x crop factor. E.g. the 18-85 f1,8 on quattro H will be equivalent to 23-45mm f2,3 on fullframe. Interesting.

I am really curious if Sigma makes this concept first introduced by Pentax K-01 (mirrorless camera with DSLR lenses) more succesful. Though theoretically interesting (immediate access to a complete portfolio of lenses), it wasn´t a success for Pentax. K-01 was blamed to be ugly and bulky, but I don´t think these Sigmas are any better.

This is definitely the weirdest ILC I have ever seen. However I like the APSH sensor, I thought is was forgotten since Canon abandoned it.

Nice, I especially like the wideangle compact, which is unique and ideal for hiking, but in my opinion a 650/850 USD enthusiast camera definitely should have a built-in EVF.
When Nikon was able to introduce 3 similar cameras at once, I see no reason why Nikon didn´t add another version(s) with EVF built-in. Apart from missing EVF everything else looks promising (lens range and speed, AF speed, external controls, touch screen etc.).

The Sigma 50-100 is great; unrivalled and unique. The luminosity diffenrece compared to usual fast telezooms with f2,8 is huge, 1,3 EV is hell of a difference.
However having used the 18-35/1,8 for almost 2 years I think f1,8 is maybe too fast, making the lens too big and heavy (and my Sigma is "only" 810g, while this new one is whopping 1490g). It could have been a bit slower, e.g. f2,2 or f2,4 (and still have the advantage over usual f2,8 zooms), wchich would make the lens either smaller and lighter, or rataining the same size it could have bigger focl range.
I love my 18-35, but I wish many times it was smaller/lighter, or with longer reach (basically something like 18-35 f2,4 with cca. 500g, or 16-40 f2,4). The same with this new one: either lighter 50-100/2,2, or longer 50-150/2,4.
Daydreaming, I know. ;-)

Johannes Zander: I want the Sigma 50-100mm F1.8 in m43 mount. Will that happen?

It wont happen. First this is a different construction made for DSLRs (different flange distance, so it would need a redesign for mirrorless). Also there is the size and weight issue, which is not a problem per se, but I somehow cannot imagine a small M4/3 camera with this Behemoth attached.

wed7: No K-mount for the 50-100, ouch!

But with the 18-35mm Sigma announced Pentax mount right from the start, even though it became available a lot later. Now there is no mention of Pentax, so I am afraid no Pentax version this time. :-(

I wonder why. The 18-35 is available for K-mount and pretty popular among Pentaxians (I have it to), so why not this one?

In reply to:

daddyo: I really look forward to seeing some test shots from someone who uses this lens properly. The bulk of these samples are worthless. Why would you do shot after shot of some distant landscape, buildings, etc., I assume hand held, at 400mm. The atmospheric distortion in those situations says absolutely nothing about the optical quality of this lens.

Why do you expect a normal photographer would shoot at 1/800s or faster? The whole point of stabilized telephoto lens is to be able to shoot at longer shutter speeds. What´s this lens´OIS benefit, 3, 4 EV? And 1/400s is only 1 EV below the advised shutter speed for non-stabilized lens.
So I think it is completely OK that DPR shot at 1/400 or longer, because that is how this lens will be shot at most. While I understand the call for those perfect shots (tripod, cable trigger etc.), most of the shots should be shot the way the majority of users will use them.
